Release Notes PN 93000694_C Connect WAN 82001660_C EOS March 31, 2009 INTRODUCTION This is a production release of firmware for Digi's Connect WAN product line. The Connect WAN family, part of the Digi Remote Site Management line of products, provides an alternative to traditional wired TCP/IP Wide Area Networks (WANs), utilizing global wireless Cellular technology to create primary and backup network connectivity. They offer an easy and cost-effective means of connecting virtually any remote location or device into the corporate IP network. SUPPORTED PRODUCTS Connect WAN 1X Connect WAN Edge Connect WAN GPRS Connect WAN GSM-R SUPPORTED CELLULAR MODEMS Within the cellular product family, Digi has continued to add support for cellular modules as vendors make updates and improvements to support the latest chipsets and cellular technology. As new modules come on the market and older ones go obsolete, Digi is committed to supporting the products we have sold and continue to sell to our customers. The level of support that we are able to provide falls into one of the following categories: 1) Full Support These modules are shipping in Digi products. An essential part of our product testing is to make sure these modules are compatible and function properly. Operational and performance issues with these modules that are found by customers will be verified, scoped and scheduled to be fixed in an upcoming firmware release. Siemens/Cinterion: MC75 REL 4, REVISION 04.001 TC63 REL 3, REVISION 03.001 Kyocera: M200, S/W VER: LF1.2.11 LF1211 PRL: 10028 2) Partial Support These modules had shipped in Digi products in the past but are no longer actively supported by the module vendor. Firmware testing no longer includes these modules, however every attempt is made to maintain support as features and improvements are implemented. Issues with these modules that are found by customers will be verified, scoped and either scheduled to be fixed or a newer, supported module offered as an upgrade option. Siemens/Cinterion: MC75 REL 2, MC75 REL 3, TC63 REL 2 3) Limited Support These modules have never shipped in Digi products and have never been part of firmware testing and verification efforts. These modules may be similar to full/partially supported modules by the same vendor and may even have been informally tested and shown to work in Digi products. Operational and performance issues with these modules that are found by customers will be evaluated and scoped to be fixed on a business case basis. Siemens/Cinterion: MC55, MC56 4) Not Supported These modules have never shipped in Digi products and are known to be incompatible. Siemens/Cinterion: TC65 ENHANCEMENTS CELLULAR ENHANCEMENTS: Add capability to report ICCID of the SIM cards. Improve mobile band and carrier selection for GSM modules. Add warning and informational text to web UI, carrier scan wizard and web help. For carrier selection, indicate discovery of 2G and 3G carriers when displayed in the carrier scan wizard. (25271, 28118, 29251) Add information to the event log and the UI (CLI, web and RCI) that indicates the user's choice of manual or automatic cellular band and carrier selection. (24942) Improve the CDMA module provisioning wizard: - Enable PPP on successful provisioning. (29078) - If network provisioning fails, offer a choice of retrying network provisioning, instead of manual provisioning. Choice of manual is available only at the start of the provisioning wizard. Add support to SNMP for mobile link up/down traps. (25003) GENERAL/OTHER ENHANCEMENTS: Add configuration web page for MEI in all MEI-capable products. Update "display techsupport" to include new and additional commands. Add the current date/time to the device status display (CLI and web UI), in addition to the uptime value for the device. For event logging, add the device uptime to end-of-log display line (both CLI and web UI), if the timestamp display for logging is other than the uptime (such as date/time). Add simple CLI to manipulate the time source management settings. See CLI command "set clocksource". Use NMEA 0183 default settings for GPS profile. These settings are: 4800,8,N,1,no flow control. (29439) BUG FIXES CELLULAR BUG FIXES: Fix a panic in the mobile carrier scan thread in the web UI. (26476) Fix a bug in which PPP statistics may display as negative values in "display pppstats". (related to 22844) Correct a bug in which e-mail alarms and snmp traps are not working for a mobile configuration change event. (26810) Fix a bug in which selecting a GPS profile for a serial port, causes the device to not connect to the cellular network. (28908) Fix a high CPU utilization issue that occurs while PPP is bringing up a connection. (29771) Fix a problem in which the network time acquired by the Siemens MC75 or TC63 modem, was improperly used to update the system's real time clock. (29646) Fix a problem in which a mobile PPP connection failed or was very slow to be established using a Siemens MC75 or TC63 modem in Europe. The incorrect 2G GSM frequencies were being configured as "preferred bands" resulting in a long delay before the correct European bands were used. (29849) GENERAL/OTHER BUG FIXES: Implement RFC-specified validation for a hostname, per the requirements for DHCP option 12. The RFCs consulted include 952, 1035, 1123 and 2132. The maximum length of the hostname is increased to 127, increased from 31. Support for a FQDN also has been implemented. Web UI help has been updated to describe a valid hostname construction. (27588) Strip carriage returns from TFTP loaded Python scripts. (26971) Add a very basic stat call for FAT FS, so we can report st_size. (22785) Add a check to the DHCP server to accept datagrams only if received on the interface being served by the DHCP server. Affects only devices with multiple LAN interfaces Fix a bug that occurs when restoring a public key: the value is set to the key plus additional bytes, resulting in a corrupt key. (27780) Add option value ranges to CLI "udpserial" command help. (29034) If a public key has been enabled for SSH, allow authentication based on the key regardless of the password setting. Dynamically generate a list of accepted authentication methods based on the configuration of the device. (27834) KNOWN ISSUES None. DOCUMENTATION ERRATA None. ADDITIONAL INFORMATION It is recommended that you perform a backup of your device's settings prior to upgrading your firmware. If you should need to revert back to a previous version of firmware, this will ensure that you will be able to restore your device to its previous settings in the event that some settings are not restored properly after downgrading the firmware. To backup your device settings, follow this simple procedure: 1) Open the web user interface and navigate to the "Administration" section and select "Backup/Restore". 2) Click the "Backup" button and select the location to where you want to save your backup file. To restore: 1) Navigate to the same section within the web UI. 2) Click the "Browse" button to select the backup file you saved in the previous steps. 3) Click the "Restore" button to upload the configuration settings contained in your backup file. On initial boot of this device, it will generate some encryption key material: an RSA key for SSL/TLS operations, and a DSA key for SSH operations. This process can take as long as 40 minutes to complete. Until the corresponding key is generated, the device will be unable to initiate or accept that type of encrypted connection. It will also report itself as 100% busy but, since key generation takes place at a low priority, the device will still function normally. On subsequent reboots, the device will use its existing keys and will not need to generate another unless a reset to factory defaults is done, which will cause a new key to be generated on the next reboot. HISTORY 82001660_C (2.8.4.7) - March 31, 2009 See ENHANCEMENTS and BUG FIXES information above. 82001660_B (2.8.1.10) - October 21, 2008 ENHANCEMENTS: Improve configuration settings implementation to use less memory, better support customized defaults and more effectively manage NVRAM. Add dynamic web page generation support for native web server from Python. Add support for Connectware Manager Web Services. Add support for file system access from Connectware Manager. Add native GPS support with Geofencing application. Add automatic failover from one network interface to another as the default gateway using customer-configurable rules. Failover-capable interfaces include cellular and Ethernet. Allow the system time to be set from the Cellular System Time. Support a Customizable Dialserve Initialization String. Split apart support for the Web Server (HTTP) service and Secure Web Server (HTTPS) service so they are managed independently of one another. Change mobile PPP interface to be always "mobile0" rather than a set of "pppX" interfaces where X varies among products. Add an on-board Primary Roaming List (PRL) update mechanism for Sierra Wireless CDMA/EVDO cellular modules. Add DMZ support to the NAT feature. Add options to set the DNS priorities and gateway priorities lists from the command-line. (27324) Added these options to "set network": gwpriority=(comma-separated interface name list) dnspriority=(comma-separated priority list) Event logging enhancements. - For "uptime", display days+hh:mm:ss versus a time in seconds. - In CLI, support user-selectable time display format. - Automatically determine appropriate time display format according to time source availability and use in a given product. Add start-up event logging in the "system" facility of these items: - product name and ID - model name (if different than the product name) - firmware (EOS) version - boot version - POST version - manufacturing VPD version (build tag) - hardware strapping value The above information is also shown by the "display device" command. Enhance the Event Logging feature to permit the user to clear the log on demand, thereby removing all log entries. This is supported in the web UI (Event Logging page) and the CLI ("display logging action=clear"). Add two new options to the CLI command "display logging": head=(lines) tail=(lines) where "(lines)" is a number of log entries to display. The "head" option displays lines from the start of the event log (the oldest entries), and the "tail" option displays lines from the end of the event log (the most recent entries). (25091) Reduce runtime memory usage, including both executable code and data. The firmware image size also is somewhat reduced. This results in more available memory in the Digi device, which can help improve performance during intervals of high memory demand operations. Improve the DHCP client capability so it persists in attempting to acquire IP configuration information if the DHCP client is enabled in the device configuration settings, and the DHCP client fails to acquire the IP configuration. This could occur if no DHCP server was available when the device booted, or if the Ethernet cable was disconnected at that time. Improve the detail reported in "display techsupport" for the network settings. Specifically, use "show network globalsettings if=*" to report everything available ("show network" is less complete). Add service provider support for Bell Mobility. BUG FIXES: Fix e-mail alarm failures. (26107, 25684, 25810) Correct a time rollover bug (wraparound to zero) in the Event Log. Fix a problem in which packets would have a zero Ethernet MAC address for up to four minutes when running in IP Pass-through mode. (26760) Fix memory leak related to RCI requests. Increase the general event log maximum message size to avoid message truncation. (24640) 82001660_A1 (2.7.0.20) - July 21, 2008 ENHANCEMENTS: Add support for the Siemens MC55 (GSM-R) air interface card. Add "show ddns" to the list of commands run by "display techsupport". (25725) BUG FIXES: None. 82001660_A (2.7.0.18) - February 12, 2008 Initial release.
